A novel easily available turn-on fluorescent chemosensor RPU based on a rhodamine-phenylurea conjugate was synthesized, which showed highly selective and sensitive recognition toward Pb(2+) in CH(3)CN and Hg(2+) in aqueous media over a wide range of tested metal ions with remarkably enhanced fluorescent intensities and also clear color changes from colorless to pink.
一种新型的、易于获得的、基于罗丹明-苯脲共轭物的荧光化学传感器 RPU 被合成出来，它在 CH(3)CN 中对 Pb(2+)和在水相中对 Hg(2+)具有高度选择性和敏感性，对测试的多种金属离子有很宽的识别范围，荧光强度显著增强，颜色从无色变为粉红色，变化非常明显。
